|Emergence of Indonesia|
Indonesia's transition to the "New Order" in the mid-1960s, ousted the country's first president, Sukarno after 22 years in the position. One of the most tumultuous periods in the country's modern history, it was the commencement of Suharto's 32-year presidency.
Described as the great dhalang ("puppet master"), Sukarno drew power from balancing the opposing and increasingly antagonistic forces of the army and Indonesian Communist Party (PKI). By 1965, the PKI extensively penetrated all levels of government and gained influence at the expense of the army. The army had become divided between a PKI-allied left-wing, and a right-wing courted by Western countries.
On September 30, 1965 six of the military's most senior officers were killed in an action (generally labeled an "attempted coup") by the so-called 30 September Movement, a group from within the armed forces. Within a few hours, Major General Suharto mobilized forces under his command and took control of Jakarta. Anti-communists, initially following the army's lead, went on a violent purge of communists throughout the country, killing an estimated half million people and destroying the PKI, which was officially blamed for the crisis.
The politically weakened Sukarno was outmanoeuvred and forced to transfer key political and military powers to General Suharto, who had become head of the armed forces. In March 1967, the Indonesian parliament (MPRS) named General Suharto acting president. He was formally appointed president one year later. Sukarno lived under virtual house arrest until his death in 1970. In contrast to the stormy nationalism, revolutionary rhetoric, and economic failure that characterised the early 1960s under the left-leaning Sukarno, Suharto's pro-Western "New Order" stabilised the economy and created a strong central government. Widely praised for economic development, the "New Order" government was also condemned for its human rights record and corruption. According to Friend, "instead of filling [Indonesians'] stomachs, [Sukarno] tried to inflame their imaginations..." whereas Suharto went on to "...cultivate full bellies and empty spirits".
Nationalist leader Sukarno had declared Indonesian independence in 1945 and was appointed president. Following an internal national revolution and struggle against the former Dutch colonial masters, Sukarno had managed to hold together the disparate country; however, his administration had not been able to provide a viable economic system to lift its citizens out of severe poverty. He stressed socialist policies domestically and an avidly anti-imperialist international policy, underpinned by an authoritarian style of rule dependent upon his charismatic personality. These policies led him to create alliances with the Soviet bloc, People's Republic of China, and to pioneer the creation of the Non-Aligned Movement of post-colonial states at the Bandung Conference. It also created a domestic political alliance with the Communist Party of Indonesia.
From the late 1950s, political conflict and economic deterioration worsened. By the mid-1960s, the cash-strapped government had to scrap critical public sector subsidies, estimates put annual inflation at 500-1,000%, export revenues were shrinking, infrastructure crumbling, and factories were operating at minimal capacity with negligible investment. Severe poverty and hunger were widespread, and Sukarno led his country in a military confrontation with Malaysia whilst stepping up revolutionary and anti-western rhetoric.
Described as the great dalang ("puppet master"), President Sukarno's position came to depend on balancing the opposing and increasingly hostile forces of the army and Communist Party of Indonesia (PKI). His anti-imperial ideology saw Indonesia increasingly dependent on the Soviet Union and China. By 1965 at the height of the Cold War, the PKI penetrated all levels of government extensively. With the support of Sukarno and the air force, the party gained increasing influence at the expense of the army, thus ensuring the army's enmity. By late 1965, the army was divided between a left-wing faction allied with the PKI, and a right-wing faction that was being courted by the United States.
Military split 
These same policies, however, won Sukarno few friends and many enemies in the Western nations. These especially included the United States and United Kingdom, whose investors were increasingly angered by Sukarno's nationalization of mineral, agricultural, and energy assets. In need of Indonesian allies in its Cold War against the Soviet Union, the United States cultivated a number of ties with officers of the military through exchanges and arms deals. This fostered a split in the military's ranks, with the United States and others backing a right-wing faction against a left-wing faction overlapping with the Communist Party of Indonesia.
When Sukarno rejected food aid from USAID, thereby exacerbating famine conditions, the right-wing military adopted regional command structure through which it could smuggle staple commodities to win the loyalty of the rural population. In an attempt to curtail the right-wing military's increasing power, the Communist Party of Indonesia and the left-wing military formed a number of peasant and other mass organizations.
Indonesia–Malaysia confrontation 
In 1963, a policy of Konfrontasi (Confrontation) against the newly formed Federation of Malaysia was announced by the Sukarno regime. This further exacerbated the split between the left-wing and right-wing military factions, with the left-wing faction and the Communist Party taking part in guerrilla raids on the border with Malaysia, while the right-wing faction was largely absent from the conflict (whether by choice or orders of Sukarno is not clear).
The Confrontation further encouraged the West to seek ways to topple Sukarno, viewed as a growing threat to Southeast Asian regional stability (as with North Vietnam under the Domino Theory). The deepening of the armed conflict, coming close to all-out warfare by 1965, both increased popular dissatisfaction with the Sukarno regime and strengthened the hand of the right-wing generals whose forces were still close to the center of power in Jakarta.
The collapse of Guided Democracy 
30 September Movement 
On the night of 30 September-1 October 1965 six senior army generals were kidnapped and executed in Jakarta by a battalion of soldiers from the Presidential Guard in an "attempted coup." The right faction among the top generals was wiped out, including the powerful Army Chief of Staff, Ahmad Yani. Around 2,000 troops from coup group occupied three sides of Merdeka Square, and commanded the Presidential Palace, radio station, and telecommunications centre, but did not occupy the east side, site of Kostrad headquarters. Calling themselves the "30 September Movement", the group announced on radio around 7am that they were trying to stop a military coup backed by the U.S. Central Intelligence Agency (CIA) that was planned to remove Sukarno from power.
They claimed to have arrested several generals belonging to a conspiracy, the "Council of Generals", that had plotted a military coup against the government of President Sukarno. They further alleged that this coup was to take place on "Army Day" (October 5) with the backing of the CIA, and that the Council would then install themselves as a military junta. Furthermore, the soldiers proclaimed the establishment of a "Revolutionary Council" consisting of various well-known military officers and civilian leaders that would be the highest authority in Indonesia. Additionally, they declared President Sukarno's Dwikora Cabinet as invalid ("demisioner").
According to one chief conspirator Lieut-Col Latief, the Palace Guards had not attempted to kill or capture Major General Suharto, commander of Kostrad (Komando Strategi dan Cadangan TNI Angkatan Darat - the Army Strategic and Reserves Command), because he was considered a Sukarno loyalist. Suharto, along with the surviving General Nasution, made the counter-allegation that the G30S was a rebellious movement that sought to replace President Sukarno's government with a Communist government. Upon hearing of the radio announcement, Suharto and Nasution began consolidating their forces, successfully gaining the loyalty of Jakarta Garrison Commander Maj-Gen Umar Wirahadikusumah and Colonel Sarwo Edhie Wibowo, the commander of army special forces RPKAD (Resimen Para Komando Angkatan Darat - Army's Para-Commando Regiment).
During the evening of October 1, RPKAD soldiers recaptured RRI and Telecommunications Building without any resistance as the rebel soldiers had retreated back to Halim Base. RPKAD forces proceeded to attack Halim Perdanakusumah AF Base on the morning of October 2, but was stopped by the rebel soldiers in a fierce gunbattle in which several fatalities were inflicted on both sides. A direct order from President Sukarno managed to secure the surrender of the rebel soldiers by noon, after which Suhartoist forces occupied the base. On 3 October, the generals' bodies were discovered at Halim and on 5 October (Armed Forces Day) a large public funeral was held.
Internal military power-struggle 
The killing of the generals saw influence in the army fall to those more willing to stand up to Sukarno and the army's enemies on the left. After the assassinations of those generals, the highest-ranking officer in the Indonesian military, and third highest in the overall chain-of-command, was Defense Minister and Armed Forces Chief-of-Staff Gen. Abdul Haris Nasution, a member of the right-wing camp. On 2 October, Suharto accepted Sukarno's order for him to take control of the army, but on the condition that Suharto personally have authority to restore order and security. The 1 November formation of Kopkamtib (Komando Operasi Pemulihan Keamanan dan Keteriban, or Operational Command for the Restoration of Security and Order), formalised this authority. However, on October 5 Sukarno moved to promote Maj. Gen. Pranoto Reksosamudra, considered a Sukarno-loyalist, to Army Chief-of-Staff.
After the promotion, The New York Times reported that an unnamed Western "diplomatic report" alleged that Pranoto was a former member of the PKI. Pranoto's alleged communism, as well as his timely promotion, led them to promote the view that the PKI and Sukarno conspired to assassinate the generals to consolidate their grip on power.
In the aftermath of the assassinations, however, Major Gen. Suharto and his KOSTRAD (Army Strategic Reserves) units were closest to Jakarta. By default, Suharto became the field general in charge of prosecution of the G30S. Later, at the insistence of Gen. Abdul Haris Nasution, Pranoto was removed and Suharto was promoted to Army Chief-of-Staff on October 14, 1965.
Anti-communist purge 
In early October, a military propaganda campaign began to sweep the country, successfully convincing both Indonesian and international audiences that it was a Communist coup, and that the murders were cowardly atrocities against Indonesian heroes. The 30 September Movement was called Gestapu (from Gerakan September Tigapuluh, "30 September Movement"). The Army, acting on orders by Suharto and supervised by Nasution, began a campaign of agitation and incitement to violence among Indonesian civilians aimed at the Communist community and toward President Sukarno himself. The PKI's denials of involvement had little effect. The regime was quickly destabilised, with the Army the only force left to maintain order.
At the funeral of Nasution's daughter Irma, Navy commander Admiral Martadinata gave Muslim leaders the signal to attack Communists. On 8 October, the PKI head office was ransacked and burned to the ground while firefighters stood by idly. They then marched demanding the dissolution of the Communist Party. The homes of senior party figures, including PKI chairman D.N. Aidit and Lukman and Nyoto were also torched. The army led campaign to purge Indonesian society, government and armed forces of the communist party and other leftist organisations. Leading PKI members were immediately arrested, some summarily executed.
On October 18, a declaration was read over the army-controlled radio stations, banning the Communist Party of Indonesia. The ban included the party itself, and its youth and women's wings, peasant associations, intellectual and student groups, and the SOBSI union. At the time, it was not clear whether this ban applied only to Jakarta (by then controlled by the Army), or the whole Republic of Indonesia. However, the ban was soon used as a pretext for the Indonesian Army to go throughout the country carrying out extrajudicial punishments, including mass arrest and summary executions, against suspected leftists and Sukarno loyalists. As the violence spread, Sukarno issued orders to try to stop it, but he was ignored. He also refused to blame the PKI for the coup, let alone ban it as the Army demanded. However, although Suharto and Nasution were increasingly suspicious about Sukarno's role in the affair, the Army was reluctant to confront the president directly because of his still widespread popularity.
Beginning in later October 1965, and feeding off pent-up communal hatreds, the Indonesian army and its civilian allies (especially Muslim vigilante groups) began to kill actual and suspected members and associates of the PKI. The killings started in the capital Jakarta, spread to Central and East Java, and later Bali. Although killings occurred across Indonesia, the worst were in PKI strongholds of Central Java, East Java, Bali, and northern Sumatra. The massacres reached their peak over the remainder of the year before subsiding in the early months of 1966. The estimates of the death toll of the violence range from over 100,000 to 3 million, but most scholars accept a figure of around 500,000. Many others were also imprisoned and for the next ten years people were still being imprisoned as suspects. It is thought that as many as 1.5m were imprisoned at one stage or another. As a result of the purge, one of Sukarno's three pillars of support, the Indonesian Communist Party, had been effectively eliminated by the other two, the military and political Islam.
In October 1965, students in Jakarta formed KAMI (Kesatuan Aksi Mahasiswa Indonesia, Indonesian Students Action Front), which called for the banning of the PKI. It was soon joined by a host of similar organizations made up of high school students, workers, artists and laborers and the like. Other targets for the demonstrators were rising prices and government inefficiency. They also demonstrated against Subandrio, the foreign minister and head of the BPI intelligence agency and the number two man in the government.
On 10 January 1966, demonstrators, including KAMI, demonstrated in front of the Provisional legislature and announced what became known as the Three Demands of the People (Tritura):
- Dissolution of the PKI
- The expulsion from the cabinet of G30S/PKI elements
- Lower prices and economic improvements
In February 1966, as anti-communist demonstrations continued, Sukarno tried to placate Suharto by promoting him. On February 21, he tried to regain the initiative by announcing a new cabinet, which included former Air Force chief Omar Dhani, who had issued a statement on October 1, 1965 initially supporting the coup. More provocatively still, Sukarno fired General Nasution from his cabinet post. The new cabinet immediately became known as the Gestapu cabinet, after the acronym coined by the military for the 30 September Movement.
Two days after the announcement, a huge crowd attempted to storm the presidential palace. The next day, while the new cabinet was being inaugurated, soldiers from the presidential guard opened fire on a crowd in front of the palace, killing student protester Arif Rachman Hakim, who was turned into a martyr and given a hero's funeral the following day.
On 8 March 1966, students managed to ransack the foreign ministry, and held it for five hours. They daubed slogans, one accusing Subandrio of murdering the generals, and drew graffiti showing Subandrio as a Pekingese dog (a reference to his perceived closeness to communist China) or hanging from gallows.
Sukarno then planned a three-day series of meetings to restore his authority. The first, on 10 March, involved the leaders of political parties. He managed to persuade them to sign a declaration warning against the undermining of presidential authority by student demonstrations. The second stage was a cabinet meeting planned for 11 March. However, as this meeting was underway, word reached Sukarno that unidentified troops were surrounding the palace. Sukarno left the palace in haste for Bogor, where later that night, he signed the Supersemar document transferring authority to restore order to Major General Suharto. Suharto acted quickly. One 12 March he banned the PKI. The same day, there was a "show of force" by the Army in the streets of Jakarta, which was watched by cheering crowds. On 18 March, Subandrio and 14 other ministers were arrested., including third deputy prime minister Chairul Saleh. That night, the radio announced that the ministers were in "protective custody".
Suharto later admitted in his autobiography that he frequently liaised with the student protesters throughout this period and Sukarno often pleaded with him to stop the demonstrations.
Political maneuvering 
On 27 March, the new cabinet lineup, agreed between Suharto and Sukarno, was announced. It included the key figures of Suharto himself as interim deputy prime minister for security and defense affairs, tasked with preventing the resurgence of communism, the Sultan of Yogyakarta Sri Sultan Hamengkubuwono IX as deputy prime minister for economic, financial and development affairs, tasked with solving the nation's economic problems and Adam Malik as deputy prime minister for social and political affairs, whose job it would be to manage foreign policy.
On 24 April 1966, Suharto gave a speech to members of the Indonesian National Party in which he spoke of the "three deviations" that would have to be corrected by the youth of the country in cooperation with the Armed Forces. These were:
- The extreme-left radicalism of the PKI and its efforts to impose a class struggle on the Indonesian people;
- Political opportunism motivated by personal gain led and exploited by the "puppetmasters" of the Indonesian Central Intelligence Board (BPI), at the time led by Sukarno ally Subandrio;
- Economic adventurism, resulting in the deliberate creation of economic chaos.
The new regime turned away from China and began moves to end the Indonesia-Malaysia confrontation, in defiance of Sukarno's wishes.
Meanwhile, Suharto and his allies continued to purge state institutions of Sukarno loyalists. The Tjakrabirawa palace guard was disbanded, and following further student demonstrations in front of the legislature building on 2 May, the leadership of the Mutual Cooperation House of Representatives (DPR-GR) was replaced and Sukarnoist and pro-communist members were suspended from the DPR-GR and the Provisional People's Consultative Assembly (MPRS), the supreme lawmaking body. Pro-Suharto replacements were appointed.
A session of the MPRS was scheduled to open 12 May, but eventually began on 20 June and continued until 5 July. One of its first actions was to appoint General Nasution as chairman. It then set about dismantling the apparatus Sukarno had built around himself. It passed several decrees, one of which was the ratification of the Supersemar, thus making revocation of it almost impossible. It also ratified the banning of the PKI and the teaching of Marxist ideology, instructed Suharto to form a new cabinet, called on Sukarno to provide an explanation for the economic and political situation in the nation and stripped him of the title "president for life". It also passed a decree stating that if the president was unable to carry out his duties, the holder of the Supersemar would assume the presidency.
The new cabinet, announced by Sukarno on 20 June, was led by a five-man presidium headed by Suharto, and including Malik and Sri Sultan Hamengkubuwono IX. It saw the dismissal of more Sukarno loyalists.
On 11 August, a peace treaty was signed, formerly ending the Konfrontasi. Indonesian announced it would rejoin the World Bank, the International Monetary Fund and the United Nations. It released political prisoners and paid compensation to the British and American governments for the damage caused to their diplomatic buildings during the demonstrations of the Sukarno era.
On 17 August, in his annual independence day speech, Sukarno claimed that Indonesia was not about to recognize Malaysia nor rejoin the UN. He also stated that he had not transferred power to Suharto. This provoked an angry reaction in the form of demonstrations, and Indonesian did indeed rejoin the UN in September, participating in the General Assembly on 28 September. Meanwhile, criticism from demonstrators became increasingly vociferous and personal, and there were calls for him to be out on trial.
On 10 January 1967, Sukarno wrote to the MPRS, enclosing a document known as Nawaksara giving his version of the events surrounding the 30 September Movement. In it, he said the kidnappings and murders of the generals had been a "complete surprise" to him, and that he alone was not responsible for the nation's moral and economic problems. This led to demonstrators calling for Sukarno to be hanged.
The MPRS leadership met on 21 January and concluded that Sukarno had failed to fulfill his constitutional obligations. In a resolution passed on 9 February, the DPR-GR rejected the Nawaksara and asked the MPRS to convene a special session.
On 12 March 1967, the special session began. After heated debates, it agreed to strip Sukarno of his power. On 12 March, Suharto was appointed acting president. Sukarno went into de facto house arrest in Bogor. A year later, on 27 March 1968, another session of the MPRS appointed Suharto the second president of Indonesia.
General Nasution was believed to have launched his own bid for power on December 16, 1965, when he won appointment to the Supreme Operations Command, and gained a grip over the traditionally civilian-held portion of the military hierarchy. It was reported that Nasution would have preferred forming a military junta to replace Sukarno. (New York Times, December 16, 1965.)
Anti-Chinese laws 
While resentment toward Chinese Indonesians by indigenous Indonesians-descended peoples of the archipelago dated back to the Dutch East Indies era, the New Order instigated anti-Chinese legislation following the quashing of the Communists. Stereotypes of the Chinese as disproportionately affluent and greedy were common throughout the time (both in Indonesia as well as Malaysia), but with the anti-Communist hysteria, the association of the Chinese Indonesians with the People's Republic of China caused them to also be viewed as a communist fifth column.
Indonesia's hitherto friendly diplomatic relations with mainland China were severed, and the Chinese Embassy in Jakarta burnt down by a mob. New legislation included the banning of Chinese language signs on shops and other buildings, and the closure of Chinese language schools, adoption of "Indonesian" sounding names, and limits on Buddhist temple construction.
A new political system 
The liquidation and banning of the Communist Party (and related organisations) eliminated one of the largest political parties in Indonesia. It was also among the largest Communist Parties in the Comintern, at an estimated 3 million members. Along with the subsequent efforts by Suharto to wrest power from Sukarno by purging loyalists from the parliament, civilian government in Indonesia was effectively put to an end by the coup countermeasures.
Strident anti-communism remained a hallmark of the regime for its subsequent 32-years.
The new regime that emerged from the upheavals of the 1960s was dedicated to maintaining political order, promoting economic development, and excluding mass participation from the political process. The military was given a strong role in politics, political and social organisations throughout the country were bureaucratised and corporatised, and a selective but effective and sometimes brutal repression was used against opponents of the regime.
A number of seats in the Parliament were set-aside for the military under as part of the dwifungsi (dual function) doctrine. Under the system, the military took roles as administrators in all levels of government. The political parties not banned outright were consolidated into a single party, the Party of the Functional Groups (Indonesian: Partai Golongan Karya), more commonly known as Golkar. Though Suharto would allow for the formation of two non-Golkar parties, these were kept weak during his regime.
Rise of Islamism 
The purging of two secularist parties, the Nationalists and the Communists, had a notable side effect of giving greater space for the development of Islamism in Indonesia. This included liberal, conservative, and extremist groups practicing Islam in Indonesia. It widely believed by observers of Indonesian history and politics that Suharto's forces whipped up anti-Communist sentiment in part by exploiting conservative Muslims' enmity of "godless" Communism to instigate a jihad against the leftists.
Improved ties with the West 
The change in regime brought a shift in policy that allowed USAID and other relief agencies to operate within the country. Suharto would open Indonesia's economy by divesting state owned companies, and Western nations in particular were encouraged to invest and take control of many of the mining and construction interests in Indonesia. The result was stabilisation of the economy and the alleviation of absolute poverty and famine conditions that had resulted from shortfalls in the rice supply and Sukarno's reluctance to take Western aid.
As a result of his elimination of the communists, Suharto would come to be seen as a pro-Western and anti-Communist. An ongoing military and diplomatic relationship between the Indonesia and the Western powers was cemented, leading to American, British, and Australian arms sales and training of military personnel.
